Be it known that I, IRVING M. HAYWARD,

,a citizen of the United States, and a resi dent ofthe city of New York, borough of Brooklyn, in the county of Kings andState of N ew York, have invented a new and Im-r proved Torch, of which the following is a full, clear, and exact description.

, yThis invention relates to an improved torch and has for an object to provide a construction which may be quickly arranged as -a torchv or arranged as an automatically heated soldering iron.

AAnother object in view is to provide a torch wherein alcohol may be readily used as a fuel.

Another object of the invention is to pro vide a construction of torch formed with an annular priming cup andan annular gener ating chamber.

and so arranged as to prevent the heat from unduly affecting the liquid part of the fuel while at the same time presenting means for conveying the fuel to the heated part of the torch for gasification.

In the accompanying drawing- Figure 1 is a longitudinal vertical section through a torch disclosing an embodiment of the invention.

Figure 2 is a sectional view through Figure 1 approximately on line 2e-2, thek same beingl on an enlarged scale.

Referring to the accompanying drawing by numerals, 1 indicates a handle which may be of wood or other desired material having a removable end 2 covering the cap 3 threaded onto the tubular container 4. The container 4 is constructed o-f metal and is adapted 'to contain a quantity of fuel 5 which fuel is preferably alcohol which may readily travel along the wicks 6, which wicks are of any suitable fabric which will cause the fuel to travel into the packing 7, which packing is preferably of asbestos. A generating head 8 is forced into the end of the container 4 and held therein by friction preferably, said generating head being pr0- vided with a bore 9 in which the tip 14 is threaded, said tipjhaving a suitable small passage-way extending therethrough, which passage-way merges into the concave portion 15. The bore 9 merges into the central bore 10 which in turn merges] into a con caved or depressed portion 10 whereby gas c, i921; serial No. 520,309.

may freely pass through 'the bore or passageway 10. A plurality of layersof wire lmesh `S co-act with member 8- for producing 4a gas generat'ng device which is-assisted by asbestos filling- 7. Byl providing layers of rwire, mesh- 8 as shown in Figure 1, the gas may freely pass ylaterally into the bore or passage-way -10 and thereby provide an ample volume or ready discharge through the tip 14. "Arranged adjacent thestip 14 is a number of apertures lwhereby a supply of air is provided for the gas immediately upon its escape from the tip] rlhe burner tubel 12 isl also provided with a number of 4air slots 17, said slots being preferably three in number so that a draughtr transversely cannot blow out the flame. f'

rllhe extreme vouter end of the tube 12 is internally threaded for receiving a threaded vextension 18 of the soldering iron or tip 19. Whenever the device` istobe used as a soldering iron, the parts are arranged `as shown the tip 19 or permits the removal of said tip i without alfectingthe mixture of the air and gas, and consequently, without affecting the production of the flame when the tip is in place. The flame is discharged directly against the end of the extension 18 and glances outwardly through the slot 17 whereby the tip is maintained at a constant heat.

In regard to the generation of lgas from the alcohol or other fuel, it will be noted that the packing 7 causes a preliminary generation while the laver of wire mesh 8 will complete the gasification of the fuel before it isy discharged out through tip 14. The chamber 15 and tip 14 permits the accumulation of a certain amount of gas so that a constant stream will be discharged through the passage-way in the tip for maintaining the flame. In order to heat the generating member 8 and associated parts when startingI the torch` a priming 'cup 20 is provided. which ,cup is au annular structure provided with a restricted Clamping section 21 made of such a diameter as to snugly fit and press against the container 4 whereby the cup is firmly held in place.

Vhen starting the torch, it is preferably. set-...on the removable end .2 offthetip. eX- tending upwardly and a quantity of alcohol or other fuel is Vdeposited in the `Cup andignitedlThisivill produee a" flame ent-irely around the upper end of the con-` tainer 4, generatingheadv 8 and associated parts whereby an even-heating will be pro` duced in a minimum time.

.i It Will bevnotedzthat the device is very rsimply `constructed and that -novalves 'arefprovided -for turning on or shuttingoif the v Y' y fueli i In casefit V'should bedesirjed kto put outthetorch before the fuehhas been eX-.
